Card holder extrusion

Abstract

A card holder extrusion mounted on a conventional card holder located in front of a shelf. One or more cards with a hooking tongue having a pair of parallel longitudinal edges are removably mounted on the conventional card holder. This card holder extrusion includes a substantially flat body having a front face, a rear face and parallel longitudinal upper and lower edges. The flat body is fastened to a conventional card holder. A card is removably mounted in the card holder extrusion. A card holder assembly results from the combination of one card holder extrusion and at least one card. A method for removably mounting the card holder extrusion on a conventional card holder and a method for mounting and removing a card from the card holder extrusion is also disclosed.

What is claimed is: 
     
       1. A card holder assembly including a card holder extrusion adapted to be mounted on a conventional card holder located in front of a shelf, the card holder assembly comprising in combination: at least one adapted to be removably mounted in a card holder extrusion, the card consisting of a sheet of flexible material having such stiffness characteristics to be easily foldable while keeping afterward its folded shape, said sheet having a free end, a front face, a rear face and a hooking tongue provided with a pair of parallel longitudinal edges that are spaced apart from each other at a given distance d 1 , the hooking tongue being formed by folding a portion of the sheet containing said free end over its rear face so that one of said longitudinal edges of the tongue is defined where the sheet is folded while the other longitudinal edge of said tongue is defined by said free end of the sheet;   the card holder extrusion adapted to be mounted on a conventional card holder located in front of a shelf comprising: (a) a flat body having a front face, a rear face and parallel longitudinal upper and lower edges;   (b) an upper and a lower member each having longitudinal upper and lower edges that are parallel with longitudinal edges of the flat body, said upper member having one longitudinal upper edge integral with the flat body, and the longitudinal lower edge, together with at least a portion of the upper member, being spaced from the front face to define an upper groove having a top and an opening, said lower member having one longitudinal lower edge integral with the flat body, and the longitudinal upper edge, together with at least a portion of the lower member, being spaced from the front face to define a lower groove having a bottom and an opening,   the openings of each groove being mutually facing and, at a given distance from each other,       the bottom of the lower groove being at a given distance d 2  from a lower edge of the upper member contributing to define the opening of the upper groove and the top of the upper groove being at a given distance d 3  from an upper edge of the lower member contributing to define the opening of the lower groove,   distance d 2  and d 3  being adapted to the following relationship:   d.sub.3 >d.sub.1 >d.sub.2       (c) means for fastening said flat body on a conventional card holder.     
     
     
       2. A card according to claim 1, wherein the sheet of foldable material is selected from the group consisting of a sheet of paper, a sheet of cardboard material and a sheet of plastic material. 
     
     
       3. A card holder assembly according to claim 1, wherein a portion of each member including the longitudinal edge above the front face is slightly turned away from said front face to enlarge the opening of the corresponding groove. 
     
     
       4. A card holder assembly according to claim 3, wherein the portion of the member space from the front face of said flat body is at a distance least slightly greater than two times the thickness of a card. 
     
     
       5. A card holder assembly according to claim 4, wherein said flat body is adapted for mounting on a conventional card holder consisting of a "C" shaped element mounted adjustment the front of a shelf and having a pair of parallel hooking members defined by each end of the "C", wherein the card holder extrusion is made of extruded plastic having elastic properties and   wherein said means for fastening said flat body comprises first and a second members projecting from the rear of the flat body, the first member being provided with a lip intended to engage a corresponding hooking member of the conventional card holder, the second member being provided with a lip intended to engage the other member of the conventional card holder, said lips being positioned and spaced apart at such a distance from each other to be respectively engaged in a bottom of corresponding hooking member of the conventional "C" shaped element.   
     
     
       6. A card holder assembly according to claim 5, wherein lips are spaced apart at such a distance that the flat body is slightly bowed outwardly when they are positioned in the bottom of each corresponding member of the conventionally "C" shaped element. 
     
     
       7. A card holder assembly according to claim 6, wherein the lip of one member projecting from the rear of the flat body consists of a layer of co-extruded material having elastic properties higher than a material used for the flat body. 
     
     
       8. A card holder assembly according to claim 7, wherein the upper member is integral with the upper edge of the flat body while the lower member is integral with the flat body at substantially mid-height thereof to thus define, between the lower member and the lower edge of the flat body, a front face portion where at least one label can be fixed. 
     
     
       9. A card holder assembly according to claim 8, wherein the sheet of foldable material is selected from the group consisting of a sheet of paper, a sheet of cardboard material and a sheet of plastic material. 
     
     
       10. A method for removably mounting at least one card of a type provided with a hooking tongue, in a card holder extrusion as defined in claim 1, introducing the longitudinal edge of the tongue defined where the sheet is folded in the opening of the upper groove until it reaches the bottom of said upper groove, and then the tongue is slid in an opposite direction until the longitudinal edge of the tongue opposite the one defined where the sheet is folded engages the opening of the lower groove and reaches the bottom of said lower groove to mount the card;   pulling the sheet until said tongue is bowed outwardly and the longitudinal edge of the tongue defined where the sheet is folded is passed over the longitudinal edge of the upper member contributing to define the opening of the upper groove, and then the longitudinal edge of the tongue opposite the one defined where the sheet is folded is removed from the lower groove to remove the card.
